Abstract

PURPOSE: To provide formed product simply by a method wherein two rubber tubes are arranged in parallel with each other between an upper and a lower mold, the space in a forming clearance is closed completely by reducing the pressure generated in a clearance for closing and the clearance between the upper and the lower mold is held at an assigned dimension.
CONSTITUTION: A reinforcing fibrous mat 9 is laid on the forming concave surface of a lower mold 7. Two rubber tubes 10, 11 where the inner pressure is given are arranged in parallel with each other over all the edge of the lower mold 7 and the upper mold 12 is mounted on the lower mold 7. A clearance 15 for closing is closed by sucking the air through a suction inlet 13 attached to the upper mold 12. The pressure in the clearance for forming is reduced by sucking the air through a suction inlet 16 attached to upper mold 12, assigned synthetic resin liquid is pressed in from a synthetic resin casting hole 17 attached on the bottom surface of the upper mold 12, an assigned amount of it is filled, cured and formed to obtain a desired plastic formed part.
